... Sternberg Astronomical Institute , Moscow University . ... Present edition unites two parts of Catalogue of interacting galaxies by B.A.Vorontsov-Velyaminov: the first part (Part 1) containing 355 systems was published in 1959 [1] and the second one (Part 2) with 497 objects - in 1976 [2].Thus two published parts of Catalogue include 852 interacting systems. ... All new of them (1162 by number) were taken from the comments to the galaxies in Morphological catalogue by Vorontsov-Velyaminov et al.[ ...

... Asteroid . ... In case you didn't hear about it, which you probably didn't: On Jan. 7, an asteroid 1,000 feet across -- nearly three times the current diameter of Marlon Brando -- barely missed the Earth, which is most likely your planet of residence. ... What if this asteroid had hit the Earth? ... As it happens, the American Astronomical Society was holding a conference in Washington AT THE VERY SAME TIME as the asteroid nearly hit the Earth. ...

... part 2 | ... Part 1 . The new concept of formation and development of the Solar system. ... Thus, the initial pulse of the rotation of a protosolar cloud of the solar system was determined as a result of the diversion of a part of the moment of the rotational pulse of the Galaxy. ... Besides this new approach to the pre-solar system as a system of the destroyed vortex structure, we can understand now a number of other peculiarities of the Solar system's structure. ...

... There are preliminary series of photometric and radio spectral observations of the above-mentioned stars, archival data on the light curves of the stars, results of the search for OH and H 2 O maser emission in IRAS point sources that possess the IR parameters similar to Miras. ... The aim is a detailed study of the maser emission variability. ... In 1996-1997, astronomical observations of Mira Ceti-type stars (miras) were carried out in three spectral ranges: optical, infrared, and radio. ...

... Latest Supernovae . ... Sorted by Name For the years covered, 7501 supernovae and 114 extragalactic novae were reported. 378 of these supernovae were named by CBAT, 1714 were given possible supernova designations, and 5409 were not reported to CBAT. 220 supernovae were found in NGC/IC galaxies, 875 were found in named galaxies 343 objects were discovered by amateurs 4 were brighter than 13th Magnitude 208 were brighter than 16th Magnitude 1080 were brighter than 18th Magnitude 1349 ...

Abstract -- Calculations are performed for the circular polarization of maser radiation from a turbulent, Keplerian disk that is intended to represent the sub-parsec disk at the nucleus of the galaxy NGC4258. ... This turbulence, along with the Keplerian velocity gradients and the blending of the three hyperfine components to form the 6 16 --5 32 masing transition of water, are key ingredients in determining the appearance of the polarized spectra that are calculated. ...

... Recall that (Voevodsky's) motives correspond to a certain "universal cohomology theory for smooth algebraic varieties". ... In 2007 I nished my preprint Dierential graded motives: weight was accepted for publication in the Journal of the Institute of Mathematics of ef Jussieu. ... I also wrote a preprint Weight structures, weight ltrations, weight spectral sequences, and weight complexes for triangulated categories (including motives and spectra) (electronic, http://arxiv.org/abs/0704.4003). ...
